What Physicians Need to Know

Core Specialization: 3D Analytics & Pre-operative Planning

Disior specializes in transforming traditional 2D medical images (CT, CBCT, MRI) into objective, numerical 3D data for comprehensive analysis, diagnosis, and patient-specific surgical planning. This forms the foundation for improved treatment outcomes and outcome assessment.

Anatomy-Specific Modules

The software offers specialized modules for various anatomical areas, providing tailored analytics. Key areas include: Foot & Ankle (hindfoot, midfoot, forefoot, hallux valgus, minimum joint gaps), Hand & Wrist (radius, ulna, carpal alignment, minimum joint gaps, fracture diagnoses), and CMF Orbital (orbital shape, volume, surface area, fracture position, maximum prolapse). It also has applicability for maxillofacial fractures.

Key Differentiator: Objective Data & Automation

Disior replaces subjective 2D image interpretation with automated, objective, and reliable 3D numerical data, minimizing discrepancies in radiology reporting and human error. This allows for consistent and comparable data-driven decisions.

Key Differentiator: Speed & Efficiency

The software accelerates patient throughput by analyzing CT or CBCT scans in 3-5 minutes, significantly reducing the hours typically spent on manual image analysis. This leads to faster diagnosis and treatment planning.

Key Differentiator: Patient-Specific & Evidence-Based Treatment

Disior enables the creation of highly accurate, patient-specific 3D models and surgical plans. This supports precise surgery execution and enhances clinical efficacy through evidence-based treatments and interventions.

Technology Stack: 3D Analytics Software (e.g., Bonelogicu00ae)

At its core, Disior utilizes advanced 3D analytics software, such as Bonelogicu00ae, which automatically converts medical images into mathematical models. This technology facilitates precise and reproducible measurements and shapes for diagnosis and planning.

Technology Stack: Virtual Planning & Visualization

The platform supports virtual treatment planning in 3D with live bone alignment measures. It also provides robust visualization tools that help clinicians explain planned procedures to patients, fostering better understanding and shared decision-making.

Physician Tip

For physicians, Disior (now part of Paragon28 Inc.) offers a significant leap from traditional 2D imaging to objective 3D analytics, fundamentally improving diagnostic accuracy and treatment planning. Expect to save considerable time on image analysis, moving from hours to minutes, allowing for accelerated patient throughput. The patient-specific 3D models and planning capabilities empower more precise surgical interventions and better predictability of outcomes. Furthermore, the ability to visualize findings in 3D can greatly enhance patient education and engagement in their treatment journey. This technology provides objective, consistent, and comparable data, reducing subjective interpretation and supporting evidence-based decision-making for complex orthopedic and maxillofacial cases. It's a tool designed to streamline your workflow while elevating the standard of patient care.
